Abstract

Назначение: энергетика и гидравлика, в частности дл  повышени  устойчивости к кавитационным автоколебани м шнекоцен- тробежных насосов. Сущность изобретени : насос содержит корпус, размещенные в нем на валу (В) 2 рабочее колесо, подвижный в осевом направлении предвключен- ный шнек (Ш) 1 , с втулкой, взаимодействующий с пружиной 5. установленной в проточке на наружной поверхности В 2. Пружина 5 снабжена кольцами 4 и 6, установленными по ее концам, закреплена передним концом на В 2 и расположена перед Ш 1 по ходу потока перекачиваемой жидкости заподлицо с втулкой Ш 1. 2 ил.Appointment: power engineering and hydraulics, in particular for increase of resistance to cavitational self-oscillations of screw centrifugal pumps. SUMMARY OF THE INVENTION: the pump comprises a housing located on the shaft (B) 2 of the impeller, axially movable upstream auger (Ш) 1, with a sleeve, interacting with a spring 5. mounted in a groove on the outer surface B 2. Spring 5 is provided with rings 4 and 6 installed at its ends, fixed with a front end at B 2 and located in front of Ш 1 along the flow of the pumped liquid flush with the sleeve Ш 1. 2 il.
